How do I setup the environment on Linux host for FreeBSD development?

[Zielonykid123]

I want to make a FreeBSD based operating system for educational purposes. What's the best way to do that? My biggest problem is that FreeBSD doesn't support ext4 and I'm not sure why but It won't mount ext2fs type file system (probably I made a mistake or something. It says that there is no such option, I can't fint ext2fs in the mount(8) manual at -t parameter). If I fixed this I could have FreeBSD environment running on qemu where I would build my code and then push the output image somehow to my host operating system and run another qemu instance from it (my host is Linux). What do you guys think of it?

Hi. The best way to build FreeBSD, is on a FreeBSD host. The tools are all built in.

As far as messing with disk formats that are compatible across the OSes, I decided a long time ago to just let each system use their native formats, and connect/mount over the network to get things between systems, which is not perfect, but it beats keeping FAT32 usb sticks around.

I suppose some people will suggest ZFS as well, it is supported on Linux and FreeBSD. That is another layer of complication added though.
